This extra carrying capacity is necessary for both flat tappet and roller cams. Automotive enthusiasts often use this 4StreetRod Performance motor oil for engine break-in, or regularly for much better fuel economy. Engine builders fully back Klotz Synthetic 4StreetRod Performance motor oil for providing a protective film of lubrication and preventing metal-to-metal contact between internal engine parts.
